SAND AND WATER FEED MECHANISM.

SPECIFICATION forming part of Letters Patent No. 315,848, dated April 14, 1885.

Application filed October 4, 1884. (No model.) I

To all whom it may concern.- I Be it known that 1, DAVID SHoRTsLEnvE, a citizen of the United States, residing at Rutland, in the county of Rutland and State of Vermont, have invented a new and useful improvement in sand and water feed mechanism for feeding water and sand or Water and shot mixed to stone-sawing or stone-rubbing or stone-dressing machines, of which the fol- IO lowing is a specification.

My invention consists in certain constructions and combinations of mechanical devices, as will be hereinafter described and specifically claimed, whereby a machine is produced with which water and sand or water and chilled-metal shot can be continuously fed or moved by a forced circulation thereof through valved chambers and pipes from a receiving and discharging chamber or hopper to points where stone-saws or stone-rubbers or stone-dressers are acting upon stone and there distributed properly upon the stone, and, after aiding the saws in cutting the stone, are automatically and continuously returned to the chamber or hopper for reuse.

This invention is such that either one, two,

or more frames containing stone-saws or stonerubbers or stone-dressers may be continuously supplied with water and sand or with water and chilled-metal shot, by means of a separate pump for each frame or one large pump for several frames, and the said fed substances may be keptin circulation, returned for continuous reuse, agitated, and deprived of all mud and refuse on their way through the receiving and discharging chamber or hopper.

In the accompanying drawings, I have represented my invention as applied to two sawframcs, each having a gang of saws; but this is only done as an illustration of one among many other ways in which it may be utilized for supplying water and sand or water and shot to stone-sawing or stone-rubbing or stone-dressing machinery,the same principle of operation being involved whether one, two, or more frames or gangs of saws, or one, two, or more sets of rubbers or dressers are supplied in ac cordance with my invention.

In the drawings, Figure 1 is a side elevation of a sawing-machine frame, gang of saws, and

stone to be sawed, with a force-pump, watersupply tank, receiving and discharging chamber, agitator, and distributingapron applied in accordance with my invention. Fig. 2 is an end view of two sawing-machine frames arranged parallel to each other, each being supplied with a gang of saws and stone to be sawed,

this view also showing a force-pump, a receiving and discharging chamber, and an agitator, the latter two being in section. Fig. 3 is a top View of the crank-shaft and drivingpnlleys for operating the force pump and agitator. Fig. 4 is a detail view of the crank-connection of the said crank-shaft and the connecting-rod of the agitator. Fig. 5 is an enlarged top view of the agitator. Fig. 6 is a horizontal section in the line mm of Fig. 2 of the receiving and dischar ingchamberbelow theagitator. Fig. 7 is ahorizontal section of the same in the line y 3!. Fig. 8 is a section similar to Fig. 6, but showing the upper valve therein in a different position. Fig. 9 is a top view of the distributing-apron, and Fig. 10 is a bottom view of the same.

A in the drawings represents a sawing-machine frame for sawing stone; B, asaw-franie, and O a force-pump of ordinary construction. The force-pump maybe attached to the frame A, and its plunger 0 operated by means of a connectingrod, c, and a crank, 0 of a crankshaft, O', suitably hung over the frame A, and provided with a driving-pulley, c and loose pulley c, and the supply-water may be drawn through a pipe, D, from either an elevated tank, d, a cistern, cl, or other suitable source, and be forced through apipe, D, into avalvechamber, E, which is below and in communication with a water and sand or water and shot receiving and discharging chamber or hopper, E. The pipes D D, at points near the pump 0, are provided with check-valves d*, in order to facilitate inspection or repair thereof. The valve-chamber E supports the conical receiving and discharging chamber or hopper E, and the communication of said chamber with the valve-chamber E is effected by means of an oscillating valve, 0, having a port or ports, e, and resting upon a fixed valve-seat, 6 having a port or ports, 6 and being secured at the bottom of the receiving and discharging chamber. The valve-seat 6 supports, by means of an ordinary socketbearing, 6 the cylindrical foot-f of a vertical seat or cushion for valve, whereby the backover the stone X being sawed. This dashshaft, F, and the valve 6 is operated through said shaft by means of a square formation thereon, fitting a square hole, 6 in the center of the valve 6. Above this valve a winged agitator, F, is fitted to the shaft, and at the upper end of the shaftacrank, f, is provided, which, by means of a suitably-jointed connecting-rod, G, is operated by a crank, 0 of the crank-shaft O. The connecting-rod G consists of a rod, and two links, g 9 the rod 9 being connected with said links by means of pins g g, standing at a right angle to each other, and each of them standing at a right angle to the wrist-pin of itslink. In other words, I the link-pin g of the link 9 and wrist-,pin f -of the agitator-crank are vertical, and the linkv pin .9 c-fthe link 9 and the wrist-pin c of the crank c are horizontal, and thus a connectingrod with universal j ointis providedfor the vertically-revolving crank c and thehorizontallyoscillating crank f. The crank c isprovided; with a slot, 0 in which the wrist-pin 0 can be; adjusted, so as to give the connecting-rod and the agitator more or less stroke,as mayi be found necessary, and open-the valves, Figs. 6, 7, 8, more or less, as desired. 'Thewinged agitator F is so fitted upon the shaft-Fthatj; it can be adjusted to any desirable height, and f there fastened by means of pins rsetscrevvs', The shaft F is kept steady'jby means of an ordinary bearing, f in across-bar, f fasta ened to the inner portion of thereceiving and? discharging chamber E above the agitatonl and in order to keep the sand in the said? chamber from entering the bearing f}, I surround it with a funnel, f of sufficientdepth and of greater height than the chamber, which funnel prevents the sand from descending upon or laterally packing around said hearing and spoiling it by grinding. The valvechamber E is at either end provided with a flap or check-valve, 6 and c, with a suitable flow of water and sand between the strokes of the pump is prevented. From the discharging end of the valve-chamber E a pipe, 'H, 'of greater diameter than the pipe Df, conducts water and sand to a suitable elevation into a pipe, I, of still greater diameter; and from discharge-pipes 13, having valves i, of this latter pipe, the water and sand are conducted upon a distributing-apron or dashboard, J, and thereby spread and distributed together board or apron J is suitably hung to the frame A by means of pendent boardsj or otherwise, and is provided with holes j for the discharge of water and sand, and withadjustable fluted distributing-chutes J, which are fastened to the lower or under sides of the inclined portions j of the apron J by means of set-screws 3' passed through slots j, and can be set parallel or spread like a fan, and moved inward or outward, so as to be long or short to suit the requirements of the case. If the stone block is large, the distributer must be expanded, and if small contracted- The unthe flow of water and sand. The-ends of the apron are provided with ordinary rims, j in order to prevent the water and sand from overflowing longitudinally at either side of the stone. The splashing of water and sand to either side of the stone may be prevented by canvas screens j suspended from the frame A and touching the upper surface of the stone just outside the gang of saws. In case only one machine is to be operated, the supply of water and sand is cut off from the other machine or machines by means of a cock, valve, orvalves,'i, provided on the pipe I.

For the collection of the water and sand flowing from the saw-grooves of the stone an ordinary chute, K, is provided, as shown, and by this chute they are conducted to the chamber E, and the surplus of water,with the mud or other substances lighter than the sand, and

vated and propelled sand against the inner surfaces of the said pipes and to the speed at which it is moved.

Operation: When a stone is to be sawed, the chamber E is filled with water and sand and the pump started, and when the water and sand begin to discharge from the pipe .t' the saws arestarted. The sand, which is gradually washed down by the water delivered from the apron J and chutes J in fine streams, is pushed, together with the water, over the ends of the stone, from whence both the-water and sand descend along the stone upon the chute K, and

from thence into the chamber E. In th-ischamber the agitator F stirs up the sand, :so as to prevent it from downward packing, and separates from it any mud or soft matter which may be mixed therewith. This stirring and washing of the sand is further promoted by upward jets of water being admitted through the opening of the valve-ports 9, during the latter part of the downward or/forcing-pump stroke, in which case the rear valve, 6, in the valve-chamber E, is closed by the back action or weight of water and sand in the pipes H and I. During the upstroke of the pump the valve-ports e are open and the valves 6 c are closed, thus giving the sand in the chamber E an opportunity to sink into the valve-chamber E previous to the next forcing stroke of the pump. When the pump begins again to force water into the valve-chamber E, the valve-ports e are closed and the sand therein is forced into the pipe H. Near the end of this water-supply stroke the valveports 6 are opened again, and the rest of the water-supply is forced'up into the chamber E, with the result above described, while the surplus muddy water runs through the overflow of the chamber into the gutter K, for preventing the backflow of water and sand and is conducted away from the machine. As the sand is gradually crushed up and becomes too fine for use, it is removed from the chamber E by the overflowing water, and the necessary supply is kept up by throwing from time to time a lot of fresh sand or shot into the chamber E. The valve of the receiving and discharging chamber might be changed in its construction and form, so that instead of being a horizontally-moving disk it might be a conical plug fitted in a conical seat, and under such construction of the valve its lower end or other portion could be set upon an inclined plane, so that as the valve-rod is turned in a forward and backward direction by the connections of the pump for the purpose of vibrating the agitator, the valve would be caused by the inclined plane to rise for the purpose of opening the discharge-passage for the sand and water or shot and water outside the valve between the wall of the chamber and the periphery of the valve, and for allowing it to descend and close said passage.

A screw or other suitable device other than an inclined plane for raising and lowering the valve simultaneously with the vibration of the agitator might be adopted. In this case the valve is made with a slip-jointabove the valve.

The above-described improved sand and water feed can with advantage be applied to all machinery which is used for cutting, grinding, or polishing with the aid of wet sand.
